方法一：    JsonConfig jsonConfig=new JsonConfig();     config.setJsonPropertyFilter(new PropertyFilter(){    public boolean apply(Object source, String name, Object value) {     if(name.equals("familyMemberRoles") || name.equals("familyMemberRels")       || name.equals("familyMemberRoles")       || name.equals("familyBaseInfos") || name.equals("familyRoleAuthorities")       || name.equals("memberIncomes") || name.equals("memberLoanouts")       || name.equals("memberOnloans") || name.equals("memberOutlaies")       || name.equals("memberRoleRels")) {                return true;     } else {      return false;     }    }   });     FamilyBaseInfo familyBaseInfo = familyBaseInfoDao.findById(familyId);   MemberBaseInfo memberBaseInfo = familyBaseInfo.getMemberBaseInfo();   HashMap hashMap = new HashMap();   hashMap.put("familyBaseInfo", familyBaseInfo);   hashMap.put("memberBaseInfo", memberBaseInfo);   JSONObject jSONObject = JSONObject.fromObject(familyBaseInfo, jsonConfig);   return jSONObject.toString();方法二：   JsonConfig jsonConfig=new JsonConfig();     jsonConfig.setExcludes(new String[]{ "handler", "hibernateLazyInitializer",   "familyMemberRoles", "familyMemberRels", "familyMemberRoles", "familyBaseInfos",   "familyRoleAuthorities", "memberIncomes","memberLoanouts", "memberOnloans",   "memberOutlaies", "memberRoleRels"});      FamilyBaseInfo familyBaseInfo = familyBaseInfoDao.findById(familyId);   MemberBaseInfo memberBaseInfo = familyBaseInfo.getMemberBaseInfo();   HashMap hashMap = new HashMap();   hashMap.put("familyBaseInfo", familyBaseInfo);   hashMap.put("memberBaseInfo", memberBaseInfo);   JSONObject jSONObject = JSONObject.fromObject(familyBaseInfo, jsonConfig);   return jSONObject.toString();
